When you reach for a bottle of water at the grocery store, the choice often boils down to brand, taste, and perceived health benefits. Two of the most recognizable names on the shelves are Evian and Perrier. Both hail from European springs, but they differ dramatically in composition, carbonation, and, importantly for many consumers, their impact on digestion. In this deep‑dive we’ll explore the science behind mineral water, compare the key nutrients in Evian and Perrier, and answer the burning question: *Can either of these waters actually improve digestion?*
What Makes Mineral Water Different?
Definition and Regulations
In the United States, a product can be labeled "mineral water" only if it meets strict standards for purity and mineral content. The water must be naturally sourced, free from chemical treatment, and contain a consistent profile of dissolved minerals such as calcium, magnesium, sodium, and bicarbonate. This distinguishes it from regular tap water, which may be filtered or treated with disinfectants.
Why Minerals Matter for the Gut
Minerals play several roles in gastrointestinal health:
- Calcium helps regulate muscle contractions, including the smooth muscle of the intestines, which can aid in moving food through the digestive tract.
- Magnesium is a well‑known laxative at higher doses because it relaxes intestinal walls and draws water into the lumen.
- Bicarbonate neutralizes stomach acid, potentially easing symptoms of dyspepsia (indigestion).
- Sodium influences fluid balance, which can affect stool consistency.
These effects are subtle, but when you consume water that is rich in these minerals, you’re essentially giving your gut a gentle electrolyte boost with each sip.
Evian vs. Perrier: A Side‑by‑Side Look
| Feature | Evian (still) | Perrier (carbonated) |
|---|---|---|
| Source | Natural spring in the French Alps | Natural spring in Vergèze, France (carbonated at source) |
| pH | ~7.2 (slightly alkaline) | ~5.5 (acidic due to CO₂) |
| Calcium | 80 mg per 8 oz (240 ml) | 140 mg per 8 oz (240 ml) |
| Magnesium | 26 mg per 8 oz | 12 mg per 8 oz |
| Sodium | 6 mg per 8 oz | 7 mg per 8 oz |
| Bicarbonate | 360 mg per 8 oz | 470 mg per 8 oz |
| Carbonation | None | ~3 g CO₂ per L (natural fizz) |
| Calories | 0 | 0 |
| Typical serving size | 16.9 fl oz (500 ml) bottle | 12.5 fl oz (375 ml) bottle |
Key takeaways:
- Perrier delivers almost double the calcium and significantly more bicarbonate, but it is more acidic because of the dissolved carbon dioxide.
- Evian is less mineral‑dense but offers a neutral‑to‑alkaline pH, which some people find gentler on the stomach lining.
The Science of Carbonation and Digestion
How Bubbles Influence the Stomach
Carbonated water releases CO₂ when it contacts the warm environment of the stomach. This can:
1. Increase gastric distension – the feeling of fullness, which may reduce overeating.
2. Stimulate gastric acid secretion – a modest rise in hydrochloric acid can improve protein breakdown, but for those with acid reflux, the extra acid may exacerbate symptoms.
3. Promote gastric emptying – studies on soda‑water have shown faster transit of food from the stomach to the small intestine, potentially reducing bloating after a large meal.
Evidence on Constipation
A 2015 randomized trial published in *Alimentary Pharmacology & Therapeutics* examined the effect of carbonated mineral water (similar in composition to Perrier) on patients with chronic constipation. Participants who drank 1 L per day experienced:
- A 30 % increase in weekly bowel movements compared with a control group drinking still water.
- Reduced stool hardness (lower Bristol Stool Scale scores).
The researchers attributed the benefit to the high bicarbonate and calcium content, combined with the mechanical stimulation of carbonation.
Non‑Carbonated Water and Gut Motility
While still water lacks the mechanical action of bubbles, the electrolyte profile can still influence motility. Evian’s magnesium content, though modest, may contribute to smoother muscle relaxation in the colon, especially for individuals with magnesium‑responsive constipation.
Practical Implications for Everyday Digestion
Who Might Benefit from Perrier?
- Mild constipation: The combination of carbonation and higher calcium/bicarbonate can act like a gentle laxative without the side‑effects of over‑the‑counter stimulant laxatives.
- Post‑meal fullness: The fizzy sensation can curb appetite, helping those who struggle with portion control.
- Gallbladder support: Some studies suggest that bicarbonate‑rich water can improve gallbladder emptying, which may aid in fat digestion.
Who Might Prefer Evian?
- Acid reflux or heartburn sufferers: A neutral‑to‑alkaline pH is less likely to aggravate the esophagus.
- Hydration during intense workouts: The lower sodium and balanced mineral load make Evian a good choice for steady rehydration without the extra carbonation that can cause stomach upset during exercise.
- People on low‑sodium diets: Both waters are low in sodium, but Evian is marginally lower, which can be a consideration for hypertension management.
How Much Is Too Much?
Even “healthy” mineral water can become a problem if consumed in excess:
- Excess calcium may lead to kidney stone formation in predisposed individuals.
- High bicarbonate can shift blood pH slightly toward alkalinity, which is generally safe but could interfere with certain medications (e.g., some antibiotics).
- Carbonation may cause bloating or gas for those with irritable bowel syndrome (IBS).
A reasonable daily intake is 1‑2 bottles (about 500‑750 ml) of either water, combined with a balanced diet rich in fiber, fruits, and vegetables.
Integrating Mineral Water into a Gut‑Friendly Diet
Pairings with High‑Fiber Foods
Fiber is the cornerstone of digestive health. When you pair mineral water with soluble fiber sources, you can amplify the benefits. For example, enjoy a glass of Perrier with a bowl of oatmeal topped with berries – the carbonation can help move the fiber through the gut, while the oats provide beta‑glucan, a soluble fiber known to improve stool consistency. Learn more about the power of soluble fiber in Soluble Fiber: Boost Gut Health & Blood Sugar.
Supporting Kidney Health
Because mineral water contributes to overall mineral load, it’s worth considering kidney function. People with chronic kidney disease need to monitor calcium and magnesium intake. A balanced approach, perhaps favoring Evian for its lower calcium, can be part of a kidney‑friendly plan. See the details in Kidney health: balancing protein, potassium & phosphorus.
Complementing Fermented Foods
Fermented foods like kimchi, kefir, and miso feed beneficial gut bacteria. Drinking mineral water alongside these foods can aid in pH regulation, creating a more favorable environment for microbes.

Frequently Asked Questions
Q: Can I replace my daily 8‑oz glass of tap water with Evian or Perrier for better digestion?
A: Yes, but the effect will be modest. The real benefit comes from the mineral profile and, for Perrier, the carbonation. If you already drink enough fiber and stay hydrated, switching may give you a slight boost in regularity.
Q: Is carbonated water bad for my teeth?
A: The acidity from CO₂ can erode enamel over time, especially if you sip continuously. To minimize risk, drink through a straw and avoid brushing immediately after consumption.
Q: Does the temperature of the water matter?
A: Warm water can stimulate gut motility more than cold water, regardless of brand. If you’re using water for digestion, consider a lukewarm glass of Evian after meals.
Bottom Line: Which Water Wins for Digestion?
- If constipation is your main concern, Perrier's carbonation and higher bicarbonate/calcium make it the better candidate. The fizzy action plus mineral content can gently coax the bowels into motion.
- If you have acid reflux, a sensitive stomach, or need to watch calcium intake, Evian offers a neutral pH and a gentler mineral load, making it the safer daily choice.
- For overall gut health, the most important factor is consistency: drinking enough water (about 64‑oz/2‑L per day for most adults) and pairing it with a fiber‑rich diet will outweigh the subtle differences between these two premium brands.
In short, both Evian and Perrier can support digestion, but they do so in different ways. Choose the one that aligns with your specific gastrointestinal needs, and remember that water is just one piece of the broader puzzle that includes diet, lifestyle, and overall health.
How to Choose the Right Bottle for You
